2023 GMC Sierra 2500HD Review

The 2023 GMC Sierra 2500HD is going to be a lighter version of the heavy-duty truck. Unfortunately, drivers can’t get the best from the vehicle, like it is the case with the Sierra 3500HD. If you don’t need 35,000 pounds of towing capacity, then the Series 2 truck will do the job.

For the 2023 GMC Sierra 2500HD, you can choose between a diesel and petrol engine. Both configurations are mighty eight-cylinder units with a lot of power. The main advantage of the Series 2 truck over the half-ton Sierra 1500 is a higher capability of working.

The engine room of the base 2023 GMC Sierra 2500HD is holding a 6.6-liter V8 petrol engine. The company recently updated this option. The displacement increase also made the truck more capable of towing. The outputs are 400 hp and 464 lb-ft of torque, which is enough to haul up to 15,000 pounds. The numbers are going up if you choose to go with a diesel engine. Duramax created a turbo version of a 6.6-liter mill, good for 445 hp and 910 lb-ft. For the Sierra 2500, this setup can tow 19,000 pounds.

If this is not enough, the Series 3 truck is offering various upgrades that will maximize the towing capacity. With the dual rear wheel configuration, the potential reaches 35,000 pounds. The new Allison transmission did a great job with the Duramax engine. Even Ram 2500 and 3500 could adopt this gearbox and replace the AISIN system.

Versions and Equipment

The new base 2023 GMC Sierra 2500HD will be called Pro. The package includes 17-inch wheels, bed steps, low-budget seats, 7-inch infotainment screen, and Bluetooth connectivity for two devices at the same time. General Motors will update the multimedia soon and it will bring higher-end features.

The SLE replaces steel wheels with alloy. Power mirrors are also added, as well as the highly-rated MultiPro tailgate with six functions. Underseat storage is very helpful, as well as the cruise control, and keyless entry. The 2023 GMC Sierra 2500HD SLT could be considered as the premium package with 18-inch wheels, LED lights, power-folding mirrors, leather seats (heated) and wireless smartphone services.

2023 GMC Sierra 2500HD AT4 and Denali

Two versions stand out from the rest of the lineup. The 2023 GMC Sierra 2500HD AT4 is an off-road oriented truck with plenty of upgrades that will make a wild adventure even more fun. A four-wheel drive is standard, as you can expect. Highlights of this package are hill descent control, skid plates, off-road suspension, and bedliner. Designers made the cabin more comfortable thanks to ventilated seats.

Still, the 2023 Sierra 2500HD Denali is the luxury truck with the best equipment General Motors is offering. There are 20-inch wheels to make the truck recognizable. Besides the MultiPro tailgate, a new trailering camera system is installed. Navigation is standard, as well as the Bose audio. The biggest downside is the price that starts at $66,000. Nevertheless, the SLT is also coming with a pretty hefty price tag of $52,000. The AT4 will cost you $60k.
